However, that's probably _not_ what you need right now. I'd rather focus on the reason _why_ GDB-stubs are entered. Try to find out how far in the initialisation you get. A BDM or JTAG debugger may be convenient for doing this. Some well placed diag_printf statements may also provide valuable insight.
